Hi,
I have a 1986 Carver 3607 with twin 350 Crusaders. My Starboard engine has been overheating this season under the following conditions...
I have replaced the Starboard side thermostat, the fresh water impeller and temp gauge. My boat has mostly been in fresh water expect for 1 year. So the mechanic removed the exhaust manifold and scrapped out the rust. After all this its still overheating as described above. And I did double check the thermostat temp with a heat gun and it is getting hot as the gauge reads.
I'm out of ideas please help.
I have a 1986 Carver 3607 with twin 350 Crusaders. My Starboard engine has been overheating this season under the following conditions...
- Start-up both motors and go for a 30 min boat ride. Temps are fine around 130-140F.
- Drop the anchor and swim for 2-3 hours
- Start motor back up and the motor will overheat within 5 mins (just after I have pulled up the anchor)
- Temp gauge will bounce between 160-180 for a couple of mins and then it will climb to 200 F.
- Shut motor off and drive back to dock under single engine
- restart motor for docking, sometimes the motor will run at 130-140F and sometimes it will climb up to 200F during docking?
